Techno-economic analysis asks whether a technology will pay, LCC asks what an asset costs to own, and cost-benefit analysis asks about net benefit to society. The same cash flows, three different questions.
Read moreWhat decides a life cycle costing tool is not the feature list but whether costs share the environmental LCA's module structure, how transparent the discounting is, and the audit trail.
Read moreThe cost-optimal framework of European building energy regulation, the EN 15459-1 global cost formula, the financial and macroeconomic perspectives, the 30/20-year calculation period, an insulation thickness scenario and the Turkish context.
Read moreService life is the parameter that moves an LCC result most after the discount rate. Where RSL comes from, the replacement formula N = ceil(T/SL) − 1, residual value, the B2/B3/B4 distinction and how long-lived products get unfairly penalised.
Read moreThe discount rate is the single assumption that moves an LCC result most. The real-versus-nominal distinction, the Fisher relation, typical ranges for public and private projects, the advantage of real terms under high inflation and a sensitivity example.
Read moreThe two standards of life cycle costing: the general methodology of ISO 15686-5, the EN 15804 module symmetry of EN 16627, cost categories, the reference study period, discounting and reporting rules.
Read moreLife cycle costing (LCC) in seven steps: analysis period and functional unit, assigning items to EN 15804 modules, the real-versus-nominal decision, discounting and NPC, EAC, a worked example and sensitivity.
Read moreLife cycle costing (LCC) is the economic twin of environmental LCA. The ISO 15686-5 and EN 16627 framework, NPC/EAC indicators, and why costs never enter the EPD.
